jB4 is a great start, and an extremely valuable tool for logging what the ECU is doing and monitoring boost levels. Most of the big guys are running it map 0 and doing ECU swaps.

Thank you for the kind comments!

Great vid. I also got the JB4 for my 2021 GT2 but I bought the kit that came with the plugs, cold air intakes, and oil catch can. I filled up with 110 octane racing gas and wow what a difference. Cat back muffler delete for the sound and maybe a few HP. Going to the drag strip tomorrow to see what it can do in the 1/4 mile. Proud to be a Stinger owner!

In fairness, you're glossing over the many other benefits of an ECU tune in terms of boost management, ignition timing, fuel correction, etc. There have been several people I know who have gone from a JB4 to a custom tune and been absolutely shocked at the performance difference, even if peak numbers didn't change that much. Peak power isn't as important as area under the torque curve.

Thanks for mentioning me! LOL And with a JB you CAN control issues with down pipes and secondaries using EWG cables. It's an add on but you can easily adapt the duty cycle to keep it from over boosting. 100's of guys are doing it now :)

Awesome video, thanks for explaining most of the different options out there for us 🙌

In a market for 19 GT2 really soon. Very exited for this car. I’m sure I’ll be looking for tunes soon after 😄

Brilliant thorough explanation. I've got a 2018 GTS (3.3 RWD) here in the UK and there isn't any following of community of the Stinger over here. Recently installed the catless full turbo back Fi exhaust system and will be looking to upgrade the intakes, Spark plugs and add an oil catch can. Holding back on the Fmic and Bov's for now as I don't want to break the bank. when all the upgrades are done I will need an ECU tune and I'm undecided whether to go for a JB4 piggy back device or get a custom dyno tune here in the UK where the Stinger is almost non-existent. Edit: I did get a quote from a dyno place, they said even with all of the upgrades they can do a stage 1 tune which will gain me about 40bhp for £595 ($820 USD) and an additional £150 for the pops and bangs which I do want to compliment the Fi exhaust.

Very thorough comparison! All while driving too. Impressive 😎

Good content as usual my brother. Doing big favors for the stinger community. And for sure give us a breakdown on how those sway bars are and how much better they are over stock. They're relatively inexpensive and should be useful. Don't forgot the summer tires too with the draggy vid :D

I went with the jb4. This car is so much fun !!! Map2 makes this daily a force to be reckoned with !

It's time to get JB4 for my G70... great video

Agree with you JB4 is the best piggy back. Easy to switch maps, great support, great price, regular updates and more... Lozic is the best ECU/TCU/AWD tune. Removal of torque limits, launch control with boost, modify shift points, no spark plug gaping required, best overall drive, best price and more...

Very well done comparison you did. I like that you weighed the pros and cons of each system. I will be getting the JB4 pretty soon for the Genesis G80 Sport so can't hardly wait for that, definitely subbed to your channel 👍

ECU and TCU tune. Its the best way to tune for sure.

The warranty thing you're kind of wrong on. Yes, you could avoid your warranty but in this country the burden is on the manufacturer or dealership to prove that whatever you did was the main cause of the issue. Don't quote me on the name and something like the Munson act which protects the consumer. Now of course they want to seem like you could void your warranty so they don't have to work on a thing now. Whether they could have you change it back to stock to do something that's a possibility. I'm not sure on the legalities of that like if there's some kind of update they have to do or some kind of change that they're doing because it was the wrong fluid they put in or whatever the issue is. Maybe that can have problems where now they need the car when it's in there stock. But it wouldn't be hard to even go against them on any of their basic claims. First off that car was built to easily handle 700 horsepower with how the engine was constructed. It was severely detuned in order to have confidence in the warranty lasting. Mine is a 10-year 125,000 bumper to bumper warranty, but again the burden would be on them to prove that you're changes specifically cause the issue now. If you don't know this act or know your rights than your screwed because you'll just take whatever they say but look it up now. This goes for America only. I don't know about Canada Australia anywhere else stingers are sold but in America we have that protection. There's actually a controller for the suspension made by the people who made disuspension for the car. I already know somebody answers. I asked the dealership. I just want to see what they understand and where they are. It helps me determine who I want working on my car. Because if they don't know certain information or they're lying, they're definitely not touching my car. Do you know of anyone that had to warranty ever voided? I don't know a single person personally . So again, do your own research. Don't just take my word for it. I am right. I know what I don't know. Now any mods you do you would always want to be able to have it go back to 100% stock so don't pierce wires always have the ability to go back to 100% stock. Cuz then you're actually altering things with most things that you do. You can say you're altering, but you're actually using what the computers capable of doing the car is capable of this. They have to detune for miles per gallon in most cases. And then you could easily use manufacturers that have special editions of cars that have more power. Well how they get that power so there's precedent set. Always look up legal definitions of words. Don't think you know what a word means. Look up what the definition is legally and then president set if there's any precedent. Like I had an issue with a car. They called on fire and they kept saying if it's due to electrical or mechanical breakdown it's not covered. Well that can mean something to you, but the legal definition of that basically says you would normally know about the issue and not do anything to stop it and continue to use the vehicle till catastrophic failure where they did not my claim originally. But once I found all that information out guess what. They reopen and gave me 33% more than the car was worth because I dared into the time again. When I'm going to the regulators next I should please deny me. I dare you. They didn't because they knew just go on KZfaq and see people that took their cars to get service done and didn't take any of their mods out. No issues

This is a really good video. Keep up the great work. Do you have a dragy? What kind of times are you running?

You're also glossing over the fact wardantys have been voided with a piggy back tune. For starters when a dealer sees swapped out spark plugs it's an indication a tune has been applied. 2nd, I've seen multiple posts of people having warranty work voided because the boost log shows a psi over stock. Just don't want someone to hear this video, buy a jb4 and assume it's gonna be all good

Thanks for sharing this video. It is very helpful.

You can definitely "void" the warranty with a piggyback because it's very easy to read the history logs on an ECU when you take it to the dealer for some issue or even a routine check/oil change, since they give such a massive window of free maintenance (1yr) and coverage (10yrs). A lot of dealers also check this, with stingers and other sports cars, because they can easily deny years of warranty service claiming that you stepped out of bounds and caused the issue. This makes them more money on non-covered parts & labor and it's hard to prove that you didn't cause the issue since there's not really any way to compare it to what "would have" happened if you didn't mess with it. The bottom line is, if you want to mod the car then either don't pay extra for the warranty or wait for ten years for it to expire lol.

Tork motorsports is in the process of a obd2 flash tune for the ecu for the stinger.

Down pipes do not necessarily need to come off or be loosened to get to the crankcase sensor with a LAP3 piggyback.

i have the jb4 and i put my primary/mid pipes. it gave me a check engine light but that was only bcuz a sensor was loose. tightened up and havent gotten a light since

Bro you forgot about lozic out of South Korea they tune ecu, transmission and awd check them out.

Another JB4 pro is the integration with flex fuel, CPI, and WMI

Do you have to gap the hks plugs or they come pre gapped?

What is better for me to buy? Please advise, knowing that I will install a full exhaust system with the dewn pipe

I’m pretty much adding all the same mods as you have with the jb4. Plan on running map 2 exclusively. I just hope everything all turns out correct without having issues. Would you suggest working my way up from 0 to 2 and make sure the logs are right? I’m planning on sharing the logs on forums because I don’t have a clue on how to read them lol.

Have you checked the Ultimate Performance down pipes? They include an o2 non-foul adapter that removes the check engine issue.

Currently researching the best tune for 2.0 Stinger. Is the Lap 3 the only one that can override the speed limiter? Live in Germany and being limited to 209Kph/130mph sucks... I'm not worried about warranty.

As far as warranties go in the United States for cars. You can make changes and do mods to your car now. If there's an issue, the burden will be on the car dealership or car manufacturer to prove that that was the sole reason for the failure. Don't quote me on the spelling but it's called the Munson act that we are protected by now the dealership may say that you voided your warning all this stuff but they can all lie but that is what we are protected by. The onus is on them the prove it

Thank you swag

Thanks very informative video! How much power can you safely push on stock engine?

Picking up a 2022 Micro Blue GT1 in mid-may/june (depending on when the dealer shows up) -- looking forward to the bolt-ons, but nervous about the tune aspect. That being said, I don't think any of these products will work with the 2022 since it's tuned differently from the factory at 368 HP.

The fastest Stinger right now will do 3.00s flat 0-60 (2.85 w/ 1ft rollout) and

If i go with the jb4, do i need to do any other mods besides the spark plugs? Only mods i have now are intakes and midpipe

What's your thoughts on VR Tunes? Looking at possibly trading in my truck for something different

I have a 2022 kia stinger gt line it’s the 2.5 liter would you recommend getting a jb4 or Lap 3 tune I just need a bit more power nothing to crazy my base horsepower is 300 and would you add a cold intake to the car also

And if I ever had an issue I would actually start arguing how their design was faulty and caused problems where what I did actually helped with longevity that wouldn't be hard to do on a lot of stuff again, always research legal definitions of words and then see what president was set in court cases using those definitions and you have everything you need to fight your case for you. Nothing else you would have to do and let alone the burdens He's on the manufacturer and car dealership that you're alteration caused this problem and was the main cause of the problem I would think even if they would try to research all that their cost that would go involved in researching that would be way more than just dealing with whatever they have to deal with. Because they couldn't use a one size fits all mentality they would have to prove each individual case.

With cold air Intake still under warranty?

How do you switch the map from the wiper speed? I have been trying to figure that out?

Wait. Tell us more about the jb4 wiper blade thing😳

Hi great video new sub and bell clicked 😉 I'm very interested in buying the Stinger seen alot of videos like these can someone tell me how strong the engine is eg internals with all these mods and addons what is the peak power the engine can handle before the internals need to upgraded cheers for time .

Can you use them spark plugs on 2015 cadenza

You can’t drive your car if you send the ecu in ?

I just got a used stinger that already had the jb4 installed....6 days later I had a check engine light ...took it to the dealer and they said it was because of the jb4 that’s causing the check engine light? Could this be true? Also can I download the app and be able to connect it to this car?

You didn't try out the racechip gts

If I run the JB4, do I have to remove it for a simple oil change at the dealership?

But on jb4 page it says it has 5yr warranty too🤨

Anyone tell me what app is being used here?

So I have a question when you take it to the dealer for regular maintenance and remove the jb4, do you also remove the spark plugs. Cause I'm sure if they see the hks plugs with the smaller gap they'll know you're doing something.

PLS HELP !!! How can I make mine go faster than 134mph!??

Wouldn't it be awesome if Kia made a limited edition of a V8 model 🤔

I recommand to speak even faster!!!!

Do a little more research some of the stuff you said wasn’t true
